Abstract:

The Montana Voting Precincts have been updated as part of redistricting in 2023. Not every county had updates following the creation of the new Montana legislative districts. This dataset will be updated as new voting precincts are obtained. The voting or election precincts were obtained from the local county offices by the Montana Department of Commerce through an FY2019 Montana Land Information Act (MLIA) Grant. The contractor used data (obtained from the counties) to digitize voting district boundaries following the recommendations of the U.S. Census Bureau Redistricting Data Program. Source data may be GIS digital data or manually digitized from maps. Key fields included 2-digit state FIPS, 3-digit county FIPS, Precinct Number, Precinct Name, County Name, and Data Date. Voting Precinct boundaries were aligned to MSDI administrative boundaries, PLSS, and parcels and projected to the Montana State Plane. According to MCA 13-3-101 the governing body of each county shall establish a convenient number of election precincts, equalizing the number of electors in each precinct as nearly as possible. According to MCA 13-3-102 the county governing body may change the boundaries of precincts, but not within 100 days before any primary or between a general election and the primary for that election. When the changes are required to make precinct boundaries conform to legislative district boundaries following the adoption of a districting and apportionment plan under Article V, section 14, of the Montana constitution or other district boundaries changed by the districting and apportionment plan, the changing of precinct boundaries must be accomplished within 45 days of the filing of the final plan.

Data Quality Information:

Completeness report: As needed

Horizontal Positional Accuracy Report: Varies on GCDB accuracy

Quantitative horizontal positional accuracy assessment:

Horizontal positional accuracy explanation: compared GDB featureclass with the source data.

Lineage:

Process step:: Imported each county shapefile dataset into the voting district feature class with topology rules consisting of no overlaps and no gaps.
Stepped through each topology error using a hierarchy of features based on the GCDB where precincts are based on PLSS descriptions and where based on other features attempted to maintain consistency with Montana framework data. Using the MSDL counties and administrative boundary cities where appropriate. Clipped or snapped the boundaries to the MSDL state boundary where appropriate. Edited the precinct number and name as necessary to match the county data.
Process step:: Added new field: COUNTY NUMBER (alphabetical county code) and updated Precinct Names
Process step:: Adjusted voting precincts to align with the 2021 CadNSDI; Project data to NAD83 (2011); Add unique identifer field (ID_UK); Add 2020 U.S. Census Bureau attribute information
Process step:: Updated McCone Voting Precincts 4 and 8 to align with the Town of Circle boundary
Process step:: Boundary and attribute updates from the Geo-Enabled Elections work
